[He gets to... decide his ending? If only it were that easy. His ending was sitting in the Ruins until he turned back into a flower, and just... staying there, until everything resets again. That was his ending. And nothing could change it.

Not even an entirely new world could fix him.

But he still doesn't understand - how is Chara alive at all?]

I don't understand any of this.

[And maybe he does sound a bit dejected by that, still.]

You're just alive? Just like that? I know humans can come back with Determination, but... it's like you said. I'm here because of the SOULs. You're... gone, Chara. At least, in the last timeline.

Even then, I didn't get it.

[The bad timelines. The ones where it's not Frisk, not truly.]

I guess it doesn't really matter how or why now, huh?
